Role of doped Ru in coercivity-enhanced LaSr_3$ thin film studied by x-ray magnetic circular dichroism
T. Harano, G. Shibata, K. Ishigami +15
The coercivity of LaSrMnO thin films can be enhanced by Ru substitution for Mn. In order to elucidate its mechanism, we performed soft x-ray absorption and magnetic…
Phase competitions in epitaxial PrCaMnO/LaSrMnO superlattices
H. Wadati, J. Okamoto, M. Garganourakis +5
We studied the charge-orbital ordering in the superlattice of charge-ordered insulating PrCaMnO and ferromagnetic metallic LaSrMnO by resona…
Imprinting magnetic information in manganites with X-rays
M. Garganourakis, V. Scagnoli, S. W. Huang +6
The effect of x-rays on an orbital and charge ordered epitaxial film of a PrCaMnO is presented. As the film is exposed to x-rays, the antiferromagnetic respon…
Origin of the large polarization in multiferroic YMnO thin films revealed by soft and hard x-ray diffraction
H. Wadati, J. Okamoto, M. Garganourakis +9
We investigated the magnetic structure of an orthorhombic YMnO3 thin film by resonant soft x-ray and hard x-ray diffraction. We observed a temperature-dependent incommensurate magn…
Bulk-like d band of SrVO3 under a self-protective cap layer
M. Takizawa, M. Minohara, H. Kumigashira +10
We have performed a detailed angel-resolved photoemission spectroscopy study of in-situ prepared SrVO3 thin films. Naturally capped by a ``transparent'' protective layer, contribut…
Photoemission from buried interfaces in SrTiO3/LaTiO3 superlattices
M. Takizawa, H. Wadati, K. Tanaka +14
We have measured photoemission spectra of SrTiO3/LaTiO3 superlattices with a topmost SrTiO3 layer of variable thickness. Finite coherent spectral weight with a clear Fermi cut-off…
